Python Formatter
Apply basic bracket-based indentation to Python code — since Python's real block structure is whitespace-defined (not brace-based), this heuristic is especially limited for Python specifically.
How to Use Python Formatter
- 1Paste your Python code
- 2Click Convert
- 3For reliable results, use black or autopep8 instead — this tool's bracket heuristic doesn't track Python's real indentation-based blocks
Frequently Asked Questions
Only partially, and less reliably than for brace-based languages. Python's actual block structure comes from the colon-plus-indent convention (if x:, then an indented block), not from {}/[]/() brackets — this tool's heuristic only reacts to brackets used for things like function calls, lists, and dicts, which don't correspond to Python's real block nesting.
Every other language here uses braces (or Ruby's end keyword) to delimit blocks, which this bracket-counting heuristic can track. Python is the one language on this site where blocks are defined by indentation itself, which this tool doesn't detect at all.
black (the standard Python formatter) or autopep8 — both are real parsers that understand Python's actual syntax and indentation rules correctly.
